Abstract

The device has a drive disc (1) which is immovably fixed in the frame (6). A tension rod (3) in the frame, as connection between the pressure rollers (4) and the fixed anchor point (5), is movably mounted. The pressure rollers are pressed radially against the periphery of the drive disc or onto the intermediate cable (2) by a force corresponding to the cable tension (T). The drive is provided by a planetary gear incorporated in the drive disc. The annular gap between the drive disc's periphery and the hole in the frame is filled by a number of roller bodies (7). <IMAGE>

Description

Die vorliegende Erfindung betrifft ein kompaktes Durchlaufseilzuggerät nach dem Oberbegriff des Anspruchs 1.The present invention relates to a compact continuous cable pulling device according to the preamble of claim 1.

Tragbare Seilzuggeräte sollen möglichst kompakt und leicht sein, ferner sollte es keine Begrenzung der Seillänge geben. Diese Forderungen werden im wesentlichen von Durchlaufwinden erfüllt, bei denen also die Weiterbeförderung des Seiles durch Haftreibung gegenüber einem Antriebselement und nicht durch die Aufwicklung auf einer Trommel erfolgt.Portable wire rope hoists should be as compact and light as possible, and there should be no limitation on the rope length. These requirements are essentially met by continuous winches, in which the rope is conveyed further by static friction to a drive element and not by winding on a drum.

Die am weitverbreitetsten, tragbaren Seilzuggeräte verwenden ein alternierend arbeitendes Klemmenpaarsystem, das im wesentlichen die Bewegungen einer Person nachahmt, welche ein Seil direkt mit den Händen zieht.The most common portable cable pulling devices use an alternating clamp pair system that essentially mimics the movements of a person pulling a rope directly with his hands.

Es sind auch Durchlaufseilzuggeräte mit einer umlaufenden Treibscheibe bekannt. Die Drehbewegung der Treibscheibe erleichtert beträchtlich die Möglichkeit, diese Geräte mit Antrieben zu versehen, es besteht jedoch das Grundproblem, daß die Mitnahme des Seiles auf einer Scheibe eine gewisse Vorspannung erfordert, die in Funktion des Reibbeiwertes und des Umschlingungwinkels nach dem bekannten Gesetz von Eytelwein ermittelt werden kann.Continuous cable pulling devices with a rotating traction sheave are also known. The rotary movement of the traction sheave considerably facilitates the possibility of providing these devices with drives, but there is the basic problem that the entrainment of the rope on a sheave requires a certain pretension, which is determined as a function of the coefficient of friction and the wrap angle according to the well-known law of Eytelwein can be.

Die bis heute angebotenen Lösungen zur Erzeugung dieser Vorspannung haben in der Praxis jedoch nicht die Herstellung von tragbaren Durchlaufseilzuggeräten erlaubt.In practice, however, the solutions for generating this pretension that have been offered to date have not allowed the production of portable continuous cable pulling devices.

Das einfachste Vorspannungssystem, das jedoch nur ortsgebunden verwendbar ist, liegt darin, eine gewisse Außenkraft im nicht ziehenden Seiltrum, z.B. bei den bekannten Spilltrieben zu erzeugen.The simplest pre-tensioning system, which can only be used locally, is to apply a certain external force in the non-pulling rope strand, e.g. to produce in the known capstan drives.

Ein anderes System zur Gewährleistung der Haftreibung besteht darin, das nicht ziehende Seiltrum beispielsweise durch Druckrollen gegen den Umfang der Treibscheibe zu drücken. Dadurch entsteht im gedrückten Bereich zwischen Seil und Treibscheibe eine Haftreibung, welche bei Betrieb des Gerätes die Vorspannung im nicht ziehenden Seiltrum sicherstellt. Die Bedingung, die die Sicherheit gegen Durchrutschen gewährleistet, ist die, daß die durch den Druckrollendruck erzeugte Haftreibung größer ist als die Vorspannung, die gemäß dem Gesetz von Eytelwein bestimmt wird.Another system for ensuring static friction is to press the non-pulling rope strand against the circumference of the traction sheave, for example by pressure rollers. This creates static friction in the pressed area between the rope and traction sheave, which ensures the pre-tension in the non-pulling rope strand when the device is in operation. The condition that guarantees security against slipping is that the static friction generated by the pressure roller pressure is greater than the preload, which is determined according to the Eytelwein law.

Die von den Druckrollen auf das Seil ausgeübte Anpressung kann z.B. über Federkraft konstant gehalten werden oder kann automatisch dem Seilzug angepaßt werden.The pressure exerted on the rope by the pressure rollers can e.g. can be kept constant via spring force or can be automatically adapted to the cable pull.

Klarerweise bieten die Systeme mit automatischer Anpressdruckanpassung eine höhere Sicherheit, da sie die erforderliche Vorspannung auch im Falle von etwaigen unvorhergesehenen Überhöhungen des Seilzuges gewährleisten.Clearly, the systems with automatic contact pressure adjustment offer a higher level of security, since they guarantee the necessary pre-tensioning even in the event of any unforeseen excessive cable pulling.

Ein Beispiel eines Seilzuggerätes mit automatischer Anpressdruckanpassung der Druckrollen ist in der italienischen Anmeldung vom 10.09.92, Nr. BZ 94 A 000 017 mit der Bezeichnung "Spilltrieb mit Vorrichtung zur Erzeugung einer Vorspannung im Seil" beschrieben.An example of a cable pulling device with automatic contact pressure adjustment of the pressure rollers is described in the Italian application of September 10, 1992, No. BZ 94 A 000 017 with the designation "capstan drive with device for generating a pretension in the cable".

Der Grundgedanke dieses Gerätes sieht eine Treibscheibe vor, die an Längsführungen in einem festen Rahmen verschiebbar gelagert ist. Die Treibscheibe wird gemeinsam mit der Antriebseinheit in Längsrichtung unter der Wirkung des Seilzuges verstellt, bis sie gegen die im Rahmen festliegend aufgenommenen Gegenrollen gedrückt wird.The basic idea of this device sees a traction sheave before, which is slidably mounted on longitudinal guides in a fixed frame. The traction sheave is adjusted together with the drive unit in the longitudinal direction under the action of the cable pull until it is pressed against the counter rollers fixed in the frame.

Dieser Grundgedanke ist an und für sich zweckmäßig und sicher, erfordert jedoch einen feststehenden und schweren Rahmen, sodaß er für ein tragbares Seilzuggerät nicht geeignet ist.This basic idea is useful and safe in and of itself, but requires a fixed and heavy frame, so that it is not suitable for a portable cable pulling device.

Die vorliegende Erfindung setzt sich daher zum Ziel, ein Seilzuggerät auszuführen, das die Verwendung von Druckrollen vorsieht, die mit einer dem Seilzug entsprechenden Kraft gegen den Umfang der Treibscheibe drücken, ohne auf eine Längsverstellung der Treibscheibe gegenüber dem feststehenden Rahmen zurückgreifen zu müssen.The present invention therefore aims to implement a cable pulling device which provides for the use of pressure rollers which press with a force corresponding to the cable pull against the circumference of the traction sheave without having to resort to a longitudinal adjustment of the traction sheave relative to the fixed frame.

Erfindungsgemäß wird dies dadurch erreicht, daß die Treibscheibe nicht verstellbar im Rahmen aufgenommen wird und indem ein im Rahmen längs verschiebbar gelagerter Zuganker vorgesehen wird, der an einem Ende die Druckrollen trägt und durch das andere Ende die auf das Gerät in der Verankerungsstelle ausgeübte Kraft überträgt.According to the invention, this is achieved in that the traction sheave is accommodated in an adjustable manner in the frame and in that a tie rod which is mounted in a longitudinally displaceable manner is provided which carries the pressure rollers at one end and transmits the force exerted on the device in the anchoring point through the other end.

Die feste Aufnahme der Treibscheibe im Rahmen bedeutet eine erhebliche Vereinfachung der Konstruktion mit einer daraus folgenden Herabsetzung des Gewichtes, wodurch damit diese Konstruktion insbesondere für tragbare Seilzuggeräte geeignet ist.The firm mounting of the traction sheave in the frame means a considerable simplification of the construction with a consequent reduction in weight, which makes this construction particularly suitable for portable cable pulling devices.

Ein Ausführungsbeispiel des erfindungsgemäßen Seilzuggerätes ist in den Figuren 1 und 2 der angefügten Zeichnung dargestellt.

  • Figur 1 stellt ein Seilzuggerät in Vorderansicht dar,
  • Figur 2 ist ein Längsquerschnitt dieses letzteren.
An embodiment of the cable pulling device according to the invention is shown in FIGS. 1 and 2 Drawing shown.
  • FIG. 1 shows a cable pulling device in front view,
  • Figure 2 is a longitudinal cross section of the latter.

Eine Treibscheibe 1 ist über ein Kugel- oder Rollenlager 7 in einem Rahmen 6 aufgenommen.A traction sheave 1 is received in a frame 6 via a ball or roller bearing 7.

Das tangential von der Treibscheibe 1 ablaufende Seil 2 neigt dazu, den Rahmen 6 in Richtung des Seilzuges T zu verschieben.The rope 2 running tangentially from the traction sheave 1 tends to move the frame 6 in the direction of the cable pull T.

Diese Verschiebung wird durch Druckrollen 4 begrenzt, die am Zuganker 3 festliegen, der den Seilzug T an die Verankerungstelle 5 überträgt.This displacement is limited by pressure rollers 4, which are fixed to the tie rod 3, which transmits the cable T to the anchoring point 5.

Die von außen auf das Zuggerät einwirkenden Kräfte sind in Figur 1 durch fett gedruckte Pfeile angegeben. Es sind dies der Seilzug T und die an der Verankerungsstelle wirksame Reaktion (-)T.The forces acting on the towing device from the outside are indicated in FIG. 1 by arrows in bold. These are the cable pull T and the reaction (-) T effective at the anchor point.

Die inneren Kräfte sind in Figur 1 mit strichlierten Pfeilen dargestellt. Diese sind:

  • Die über die Drcuk-bzw. Gegenrollen 4 radial auf die Treibscheibe einwirkende Kraft T und durch Zwischenschaltung des nicht ziehenden Seiltrums, derart, daß wie beschrieben, eine Haftreibung zwischen Seil 2 und Treibscheibe 13 entsteht, welche ihrerseits es erlaubt, die für die Mitnahme des Seils erforderliche Vorspannung T zu erhalten.
  • In der Treibscheibe und daher auch im fest verbundenen Rahmen durch Betätigung der Treibscheibe, wirkt das Drehmoment r x T, das durch das am Zuganker 3 vorliegende Kräftepaar A x a im Gleichgewicht gehalten wird, dadurch gegeben, daß die Kräfte T bzw. (-)T vom Arm r beabstandet sind.
The internal forces are shown in FIG. 1 with dashed arrows. These are:
  • The over the Drcuk or. Counter rollers 4 radially acting on the traction sheave force T and by interposing the non-pulling strand of rope, such that, as described, a static friction arises between the rope 2 and the traction sheave 13, which in turn makes it possible to obtain the pretension T required for driving the rope.
  • In the traction sheave and therefore also in the firmly connected frame by actuation of the traction sheave, the torque rx T acts, which is kept in equilibrium by the pair of forces A xa present on the tie rod 3, given that the forces T and (-) T from Arm r are spaced.

Der Antrieb erfolgt vorzugsweise über einen Antriebsmotor 8, der mit dem Rahmen 6 fest verbunden ist.The drive is preferably carried out via a drive motor 8 which is fixed to the frame 6.

Der Antrieb kann jeglicher Art sein, beispielsweise elektrisch, hydraulisch oder pneumatisch.
Selbverständlich kann das Gerät auch durch einen geeigneten Handantrieb betätigt werden. Üblicherweise wird die Zwischenschaltung eines Untersetzungsgetriebes zwischen Antrieb 8 und Treibscheibe 1 erforderlich sein.The drive can be of any type, for example electrical, hydraulic or pneumatic.
Of course, the device can also be operated by a suitable manual drive. Usually, the interposition of a reduction gear between drive 8 and drive pulley 1 will be necessary.

Aus Platzgründen kann dieses Untersetzungsgetriebe unmittelbar in der Treibscheibe eingebaut sein. Das in der Zeichnung gezeigte Beispiel stellt diese Lösung dar, d.h. ein in der Treibscheibe eingebautes Planetengetriebe.For reasons of space, this reduction gear can be installed directly in the traction sheave. The example shown in the drawing represents this solution, i.e. a planetary gear built into the traction sheave.

Das Untersetzunggetriebe besteht aus einem mit dem Antrieb 8 gekuppeltes Sonnenrad, aus einigen Planetenrädern 10 sowie aus einem innen verzahnten Zahnkranz 12, der aus der Treibscheibe 1 ausgearbeitet ist. Der Planetenträger ist im vorliegenden Fall identisch mit dem Rahmen 6, und daher mit den Achsen der Planetenräder 11 fest verbunden, während der innen verzahnte Zahnkranz 12 umläuft.The reduction gear consists of a sun gear coupled to the drive 8, a few planet gears 10 and an internally toothed ring gear 12 which is worked out from the drive pulley 1. In the present case, the planet carrier is identical to the frame 6, and therefore firmly connected to the axes of the planet gears 11, while the internally toothed ring gear 12 rotates.

Zur Erhöhung der Haftreibung zwischen Seil und Treibscheibe kann die Seilrille 13 einen keilförmigen Querschnitt erhalten.To increase the static friction between the rope and traction sheave, the rope groove 13 can have a wedge-shaped cross section receive.

Ein weiterer, integrierender Bauteil des erfindungsgemäßen Seilzuggerätes ist eine Feder, welche die Druckrollen 4 über den Zuganker 3 gegen den Umfang der Treibscheibe drückt.Another integrating component of the cable pulling device according to the invention is a spring which presses the pressure rollers 4 against the circumference of the traction sheave via the tie rod 3.

Die durch die Feder 14 ausgeübte Kraft kann gegenüber der von der höchsten Seilzugkraft T ausgeübten sehr klein sein. Sie dient dazu, die Mitnahme des Seils am Beginn, wenn der Seilzug T noch null ist, sicherzustellen.The force exerted by the spring 14 can be very small compared to that exerted by the highest cable tensile force T. It is used to ensure that the rope is carried at the beginning when the cable pull T is still zero.

Das erfindungsgemäße Seilzuggerät sieht überdies eine Seilführung 15 vor, die die einwandfreie Position des Seils gegenüber der Seilrille 13 beim Auflaufen bzw. Ablaufen in der Ausgangsposition gewährleistet.The cable pulling device according to the invention also provides a cable guide 15 which ensures the correct position of the cable in relation to the cable groove 13 when it runs up or down in the starting position.

Diese Seilführung muß geöffnet werden können, d.h. in zwei geteilt sein. Diese Zweiteilung ist zeichnerisch nicht dargestellt.This rope guide must be able to be opened, i.e. be divided into two. This division into two is not shown in the drawing.
